Error Code P216F: What It Means & What To Do?

OBD Code P216F - Fuel Injector Group F Circuit High

<<See All OBD Codes

Is your vehicle’s Check Engine Light illuminated? Are you experiencing sudden decrease in engine power and acceleration? Is there a drop in the fuel economy with increased level of emissions? All these indicate problem with the fuel delivery system and the Powertrain Control Module, thus flashing OBD Code P216F error.

Learn More About OBD Error Code P216F

OBD code P216F gets set when the PCM detects the Group F fuel injector circuit emitting high voltage, meaning that the injector is at its maximum limit to adapt to the changes in the fuel demand by the PCM and has exhausted its limit to adapt further. It is important to note that the injector is designed to adapt to the engine’s varying fuel needs based on the external factors faced by the vehicle. It can be weather change, terrain change, temperature difference, etc.

Thus, when the ECM notes that the fuel injectors learning values are beyond the normal operating parameters, it sets the above stated OBD code.

What causes this problem with the Fuel Injector Group F Circuit High?

  • Vacuum Hose Leaks
  • Fuel filter faulty or clogged
  • Fuel pressure sensor faulty
  • ECM/PCM error requiring reprogramming
  • Problematic fuel injector
  • Worn/cracked piston rings
  • Fuel pressure regulator problematic

Replace/Repair These Parts To Fix Code P216F

  1. Engine Control Module – ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
  2. Powertrain Control Module – Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
  3. Oxygen Sensor – Inspect for faulty O2 sensor that can affect the engine combustion process and the exhaust emissions. Thus, it is important to understand its importance and replace faulty oxygen sensor now!
  4. Diagnostic Tools – Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment from us!
  5. Fuel Injector – Bad fuel injectors can cause starting issues, poor idles and affected performance. Thus, the replacements are in order. Buy new fuel injectors now!
  6. Fuel Sender Connector – Always check for faulty sender connectors as they can hinder the fuel delivery system, leading to lean or rich engine conditions, causing performance issues. Thus, replace faulty fuel sender connectors now!
  7. Spark Plugs – Spark plugs are easy to replace and are inexpensive too. They help in delivering the electric current from the ignition system to the combustion chamber of the spark ignition engine to ignite the compressed air to fuel mixture by an electric spark. Thus, replace them now!
  8. Fuel Tank Pressure Sensor – The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It is part of the evaporative emissions system and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap. Replace faulty pressure sensor now!

Easy Diagnosis Of Engine Error OBD Code P216F

Here are some steps which you should follow in order to diagnose this P216F fault code:

  • Inspect and resolve MAP and MAF related code error that might also get stored in the PCM along with this code, which can solve the problem easily.
  • Check the fuel injection area for any corrosion or leakages on the exterior and if found, suspect it to be failed.
  • Make use of tools like a diagnostic scanner, digital volt/ohmmeter, and auto motive stethoscope.
  • Connect the OBD scanner to retrieve all the error code and freeze frame the data. Then, test run the vehicle again under same circumstances to see if the code returns to make sure which codes are persistent (in case of more than one code).
  • Do a sound test to hear if the fuel injector working and if there is no continuous clicking sound, suspect for failed of clogged fuel injector.
  • Use the DVOM to test for voltage and a ground pulse, when the engine is running. If no voltage is discovered at the connector of the fuel injector in question, use the DVOM to test system fuses and relays. Replace fuses and/or relays as needed.
  • If everything seems to work fine, then check for faulty PCM and replace or reprogram as required.

Common Mistakes When Diagnosing The P216F Code

There can be many other factors causing this problem rather than directly blaming the injection system completely. Always check for faulty wirings, and fuses as well as MAP/MAF sensor and O2 sensors for error too. Take help of professional mechanic to solve OBD code problem as this will ensure avoidance of misdiagnosis and can also help to reduce the costs associated with the repairs.

  • Fuel injector failure
  • Powertrain Control Module (PCM) failure
  • Wiring and connector issues in relation to the sensor and circuits
  • Damaged or clogged fuel filter
